Pasture-based ruminant production systems are common in certain areas of the world, but energy evaluation in grazing cattle is performed with equations developed, in their majority, with sheep or cattle fed total mixed rations. The aim of the current study was to develop predictions of metabolisable energy (ME) concentrations in fresh-cut grass offered to non-pregnant non-lactating cows at main...

Two experiments were conducted to evaluate the nutritional value of three cultivars (Promore, Kiev mutant and Ultra) of white lupins (Lupinus albus L.) for broilers. In experiment 1, the apparent metabolisable energy (AME) and ileal amino acid digestibility coefficients of the three cultivars were determined. The cultivar effects were significant (P < 0.05) for AME, but the ileal amino acid dig...

A total of 364 female Ross 308 chicks (1 d old) were used in the present study conducted in floor pens to investigate the effects of graded levels of supplementary bacterial phytase on dietary energy utilisation and growth performance. For this purpose, four maize-soyabean-based diets were offered to the birds from 0 to 21 d of age. These included a suboptimal P negative control (NC, 3.0 g/kg n...

Methane production in Muzaffarnagari sheep was studied using open circuit respiration calorimetry technique. Twelve rams were divided in three treatment groups of four each and were fed at about maintenance with diets having three roughage (oat hay) to concentrate ratio (R : C), i.e. 92 : 8 (group I), 50 : 50 (group II), 30 : 70 (group III). Concentrate mixture was formulated to contain 93% cru...

Maternal nutrition during the period of early organ development can modulate the offspring's ability to metabolise excess fat as young adults when exposed to an obesogenic environment. This study examined the hypothesis that exposing offspring to nutrient restriction coincident with early hepatogenesis would result in endocrine and metabolic adaptations that subsequently lead to increased ectop...

Bu çalışmanın amacı, kuzu besi rasyonlarına meşe palamudu ilavesinin, in vitro gaz ve metan üretimi ile sindirim derecesi, mikrobiyal protein sentezleme etkinliğine olan etkisini üretim tekniğiyle belirlemektir. proje kapsamında %0, 10, 20 30 oranında rasyonuna katılmıştır. Kuzu ilavesi üretimi, derecesini azaltırken, taksimat faktörünü, sentez etkinliğini artırmıştır. Gaz değerleri sırasıyla 8...

the study was conducted to know the effect of flushed feeding on estrus synchronization and conception rate of holstein ílocal crossbred cow’s after using the gnrh (fertagyl) and pgf2α hormone. as a representative sample 20 holstein ílocal crossbred cows were chosen from chittagong cantonment military dairy farm in bangladesh and the experimental work was carried out for 60 days. ten cows were ...
